Take-it-as-it-is

Rui Hang's decision to sit in on the trial was not a whim.

On the first day after returning to Earth, he was ready to attend classes with his students.

Firstly, he can supervise these students and prevent them from doing something out of line in class, and at the same time increase the chances of them listening carefully. Secondly, he himself has a strong desire to acquire scientific knowledge.

Compared to buying books and studying on your own, the teachers in school are experienced and know how to explain each knowledge point in a simple and easy-to-understand way. It would be a waste if you don’t know how to make use of such excellent educational resources.

Like the students who were the ruling class, Ruihang also had his own country. Among them were the demons who were once the absolute villains and frightened the entire Parnaki, and the various races who were once slaves under the demons.

Compared with other students in the class, the only thing that made Rui Hang lucky was that his throne came from the hereditary system. He was the lord of the demon clan with absolute ruling power and did not need to engage in intrigue for the top position. Moreover, because of the powerful bloodline power of the demon clan, he possessed powerful strength comparable to that of an adult dragon from birth.

But power is exactly what the demons have the most. No matter how strong the demon lord is, he is just a juvenile. There is no need to intrigue for the top position, but it does not mean that there is no one who can replace him. Moreover, as a pure-blooded human living in a materialistic worldview, it takes enough time to adapt to an idealistic world built on magic power, not to mention the crucial matter of learning a new foreign language.

Therefore, during the first fifty years of the time travel, Rui Hang's entire time was occupied by cultivation, learning the culture of the new world, searching for students who might have traveled to Parnaki like himself, and guarding against assassinations that could occur at any time.

As his strength grew, fewer and fewer people wanted to replace him, and the students scattered in the other world were gradually found. Rui Hang, who had finally breathed a sigh of relief, devoted himself to reversing the internal structure of the demon clan, liberating other clans who were slaves, and twisting the entire demon world "Relthad" into a whole.

Several decades later, thanks to his efforts, the frequent civil wars within the demon clan finally ceased. The world's view of the demon clan also gradually changed from a brutal "villain" that only brought war and fed on other races to a warlike but not very dangerous clan in the Parnaki.

With internal and external stability, Rui Hang finally had the time to start developing core technology, but it was not until then that he realized that he knew nothing about this area.

He was good at economic development, political systems, party struggles and factions, but he was completely clueless about inventions and creations.

Rui Hang had thought about using some common sense scientific knowledge and finding some active-minded craftsmen to conduct research. However, everything in Parnaki was based on magic power, and the scientific research results that required countless generations of hard work were just a wave of the hand for powerful magicians. The people of Parnaki could not understand his idea of ​​studying science from scratch, and Rui Hang could not rely on his meager scientific knowledge to systematically explain the reasons to these people.

Even if some craftsmen accepted his ideas and were willing to try to study them, the parameters of the two worlds were not necessarily the same. Without scientific instruments to perform systematic measurements, any value he gave could be a false guide.

Rui Hang had also thought about asking students for help. He knew that some students in his class were very good at inventions, but in this world where science had not even sprouted and magic existed but was quite barren, even scientific knowledge that existed as "truth" was a vital national resource.

He shares political science knowledge with students because of his sense of responsibility as a teacher, but it does not mean that students need to do the same.

Fortunately, students are also willing to share their knowledge with other students in the class. In return, they will tacitly keep this knowledge and wait until the students who share the knowledge create enough value with it before putting it into use.

But relying on others like this is not reliable after all. It is most reassuring to have knowledge in your own hands.

It's not just Rui Hang. Others in the class such as Ou Wenna, Sun Jingshu, etc. also know this truth very well. They have been the hardest-working students in the past two days.

...

When Guo Yingxue entered the classroom, the first person she saw was her head teacher Rui Hang, who was sitting in the last row with a focused expression.

As an experienced physics teacher, Guo Yingxue was not surprised, but was a little puzzled. Usually, the class teacher would audit the class before the big exam, to supervise the students who were absent in class, or to evaluate the teaching quality of the teacher. There was still a month before the monthly exam, right? Why did he start auditing now?

It was just that Rui Hang was always responsible, so Guo Yingxue didn't think much about it, and thought that he was working hard for the teacher assessment at the end of this year. So she made eye contact with Rui Hang, nodded slightly and greeted him, and then focused on the lecture. However, it didn't take long for Guo Yingxue's eyes to be completely attracted by Rui Hang, and she couldn't look away.

——This young head teacher, who has already been named "Excellent Teacher of the School", crossed one leg and placed a notebook on his knee. His brows were sometimes slightly frowned, sometimes relaxed, and sometimes wrinkled into the shape of a "川" character. His pair of black eyes were full of thought, and his gaze sometimes swept across the class. His right hand kept writing, obviously taking notes.

"As expected of you, you are the youngest homeroom teacher in our school. You are really ambitious."

Guo Yingxue sighed in her heart: Although Mr. Rui is a generation younger than me, I am still far inferior to him in terms of work attitude. No, I have to show some attitude and not let Mr. Rui look down on me.

Thinking of this, Guo Yingxue became extremely alert, her eyes became sharper, and she wrote more and more on the blackboard.

For a moment, the only sounds in the class were the female teacher's sharp lecture and the rustling sound of the pen hitting the paper.

Zhou Xun, who was sitting in the last row and very close to Rui Hang, looked up from his notes, unable to hide his curiosity. While Rui Hang was concentrating on taking notes, he secretly glanced at Rui Hang's notebook like a thief.

The white paper was filled with neatly written notes, which were actually a one-to-one replica of the writing on the blackboard, and was filled with marks in marker pen and countless small "?"s.

Obviously, Rui Hang had no idea what was important in the blackboard writing, and could not understand the specific meaning of what Guo Yingxue was teaching. He could only use the simplest method and copy down all the content first.

The other piece of paper half covered by his palm was much more empty. It recorded the quiz that Guo Yingxue had just assigned. The questions were centered around the blackboard writing and were not difficult. Even those who had not attended classes for hundreds of years could rely on the residual knowledge in their brains and draw inferences from what Guo Yingxue taught them.

However, for Rui Hang, this question still exhausted him.

Those scattered and irregular symbols and numbers seemed to be a reflection of his inner self, full of disorder and confusion. After going through untold hardships, he was unable to achieve the simplicity of simplifying things.

Zhou Xun: “…”

It turns out that the omnipotent teacher Rui also has times when he is at a loss!

Zhou Xun suddenly had an epiphany and understood the meaning of Rui Hang's many expressions.

——Eh, I don’t seem to understand.

——Oh, I finally understand.

——Shit, which country’s Bible are you talking about?!

Rui Hang has always been very sensitive to other people's gazes and emotional changes due to his many years as a demon king. He stopped taking notes, squinted at Zhou Xun, and lowered his voice: "What are you looking at?"

Zhou Xun: "...Nothing!"

Faced with Zhou Xun's curiosity, Rui Hang had no intention of hiding anything. As a typical liberal arts student who chose political science and administration as his major in college and had basically not been exposed to physics since the high school entrance examination, Rui Hang did not think it was shameful that he could not understand the content of physics class. It was like talking about Hegel with a physics student and analyzing Hobbes's social contract theory - why torture each other?

Unfortunately, for the sake of that uncertain future, even though this knowledge gave him a headache, he still had to bite the bullet and continue learning.

Anyway, I am the class teacher. No matter how badly I do in school, who dares to laugh at me?

Rui Hang thought with peace of mind.

But it is really troublesome that I can't understand it all the time. Otherwise, I might as well buy some junior high school physics textbooks during the lunch break and start from the beginning.

Just as Rui Hang was thinking about this, a physics class that had made many people uneasy finally ended with the belated bell.

Rui Hang put down his notebook and prepared to go out for some exercise to relax his slightly stiff body after sitting for a long time, but he saw Guo Yingxue walking out of the door right after him, and walking straight towards him after leaving the classroom.

What happened? Did she think my auditing disturbed her class? Or did she want to check what I learned after class?

...What was the name of the knowledge point she mentioned in class? It seemed to be called Newton's Second Law, but how do I recite the formula?

While he was thinking hard, Guo Yingxue had already walked in front of him. For some reason, her expression looked a little solemn: "Teacher Rui, it happens that you are here too. Regarding this class..."

"Teacher Guo, you taught very well today. I benefited a lot from it." Rui Hang's heart tightened, fearing that Guo Yingxue would ask questions about the class content. A trace of imperceptible embarrassment flashed in his eyes, and he quickly interrupted her.

Guo Yingxue: “???”

Although Guo Yingxue was a little surprised by Rui Hang's irrelevant question, she didn't think too much about it. She sighed, and a deep cloud of worry appeared on her brows: "Thank you for your evaluation, Mr. Rui. It would be great if all the students in our class were as focused on their studies as you are."

Rui Hang keenly sensed that Guo Yingxue had something to say, and the anxiety of not being able to answer the question finally dissipated. He quickly returned to his usual calmness and asked with concern, "Did anything happen to the students?"

Guo Yingxue pursed her lips and nodded seriously: "I found that there are some problems with the physics homework of my classmates. When I was marking the homework this morning, I found that the homework of the classmates in the class was very similar. Teacher Rui, it seems that the phenomenon of copying homework in our class should not be underestimated!"

Rui Hang: “…”

So embarrassing!

He thought: How come they are all so grown up and can't even copy homework? They were discovered in just one day!

"Teacher Rui, the junior college entrance examination will be in January. There are only four months left. If you don't hurry up, it will be too late!"

"Teacher Guo, you are right!" Rui Hang quickly put away his complaints and made himself look equally worried: "It's already this critical moment, and the children really don't know the seriousness of the matter."

“Isn’t it!”

Having said this, Rui Hang suddenly sighed: "In the final analysis, this matter is my fault."

"What do you mean, Teacher Rui?" Guo Yingxue was puzzled.

"Isn't the Mid-Autumn Festival coming soon? Our class is going to perform a play. The rehearsal pressure is already high, and the students know that I care a lot about the sports meeting. Now they are all working hard to prepare for the sports meeting. When time is tight, it is natural that some students will do something sneaky."

"Oh, you're already in the second year of high school and you're still performing in a drama?" Guo Yingxue disagreed.

"Aren't the leaders coming to review it soon? Compared to singing and dancing, the drama at least looks more serious." Rui Hang blinked and said a little cryptically.

Guo Yingxue understood immediately, and her eyes suddenly showed a hint of helplessness.

"Ah, you said he was right too. How can such superficial things be more important than the students' studies?"

But once the topic involved You know who in school, Guo Yingxue couldn't say anything. She never thought that all this was just Rui Hang trying to shirk responsibility for the students and force the blame on the principal.

"In this case, I won't pursue this matter too much. But we still need to take care of what needs to be taken care of. Teacher Rui, you need to pay more attention to this matter."

Seeing that Guo Yingxue's attitude had relaxed, Rui Hang nodded quickly and said a few words of comfort in the same tone as hers, which made Guo Yingxue leave contentedly.

Watching Guo Yingxue's departing back, Rui Hang was silent for a moment, his gaze silently drifted into the classroom, and his eyes quickly became sharp.

These little bastards!
